“…In addition, according to relevant research, the water-insoluble portion of pyrolysis oil can also be used as a component of composite asphalt binder. This means that renewable biomass-derived resources will replace fossil asphalt [54]. At present, the industrial application of pyrolysis oil has attracted wide attention.…”

Pyrolysis of raw pine bark, pine, and Douglas-Fir bark was examined. The pyrolysis oil yields of raw pine bark, pine, and Douglas-Fir bark at 500 °C were 29.18%, 26.67%, and 26.65%, respectively. Both energy densification ratios (1.32–1.56) and energy yields (48.40–54.31%) of char are higher than pyrolysis oils (energy densification ratios: 1.13–1.19, energy yields: 30.16–34.42%). The pyrolysis oils have higher heating values (~25 MJ/kg) than bio-oils (~20 MJ/kg) from wood and agricultural residues, and the higher heating values of char (~31 MJ/kg) are comparable to that of many commercial coals. The elemental analysis indicated that the lower O/C value and higher H/C value represent a more valuable source of energy for pyrolysis oils than biomass. The nuclear magnetic resonance results demonstrated that the most abundant hydroxyl groups of pyrolysis oil are aliphatic OH groups, catechol, guaiacol, and p-hydroxy-phenyl OH groups. The aliphatic OH groups are mainly derived from the cleavage of cellulose glycosidic bonds, while the catechol, guaiacol, and p-hydroxy-phenyl OH groups are mostly attributed to the cleavage of the lignin β–O-4 bond. Significant amount of aromatic carbon (~40%) in pyrolysis oils is obtained from tannin and lignin components and the aromatic C–O bonds may be formed by a radical reaction between the aromatic and aliphatic hydroxyl groups. In this study, a comprehensive analytical method was developed to fully understand and evaluate the pyrolysis products produced from softwood barks, which could offer valuable information on the pyrolysis mechanism of biomass and promote better utilization of pyrolysis products.

“…5, the pyrolysis process has preserved the porous structure of the wood, opening up a range of possible applications, such as acidic catalyst or activated carbon. 45,46 The bitumen industry has seen a growing interest for bio-oil applications in recent years, 13,14,[47][48][49] driven by increasing costs of raw petroleum-based materials and by the decreasing share of bitumen coming from more and more efficient petroleum refineries.…”

“…11,12 However, other applications can be of interest, such as bitumen and asphalt, that are gaining in popularity mostly due to a higher demand and market evolution. [13][14][15][16][17][18][19] For both strategies, one of the main challenges faced by the pyrolysis oil option is its high water and acidity contents. [20][21][22] The unit also needs to be compact and mobile enough to be operated close to the harvesting areas and to follow them as they change each year, minimizing transportation of raw residues.…”

Forest biomass is an attractive alternative resource to fossil ones, renewable and without environmental impacts as long as forest residues are considered. Collecting and transforming forestry residues into value-added products is a challenge as they are usually scattered over a large area. To reduce the economic and environmental cost of forestry residues transformation, in-situ energy densification is a powerful solution. To achieve efficient energy densification of forestry residues and transformation for industrial use, a new pyrolysis unit designed by the University of Western Ontario is used to produce low water content pyrolysis oil and high-quality biochar. Bio-oil with 8 %wt water content is produced. Energy density of the bio-oil is compared to other densification methods, showing the interest of pyrolysis to increase the energy density of biomass. High quality and free of sand biochar is also produced. Various properties of the bio-oil and biochar are explored to determine its potential for various industrial applications in the scope of a major biorefinery project in La Tuque, Québec.
